itemscontrol

问题 Is it possible to group items in a ItemsControl or Listbox in Silverlight? These controls are bound to a DomainDataSource. Or are there any 3rd party controls that do this? UPDATE: This is the sort of UI I am trying to create. 回答1: You can do this by using nested ItemsControls bound to a PagedCollectionView. Say I have a datasource - MyItems - with fields: Category , Section and Option . I can create a PagedCollectionView from an IEnumerable(of MyItems) and tell it which fields to group by.

问题 I have some data that I want to present in a FlowDocument . This will basically be a view that explains the data in a friendly way, with section headers, paragraphs of text, etc., and which I will display in a FlowDocumentScrollViewer. To this end, I would like to create a bulleted list ( <List> ) out of the contents of an ObservableCollection . I know how to do that with ItemsControl , but how do I do it for ListItem elements in a FlowDocument , since they're part of the TextElement class

问题 Ok, I have an ItemsControl binded to a List<IComparableObject> , each second the List objects change, so I have to resort them, so each second I call the List.Sort() method. Checking in the Watch panel in VS2008, I can tell the List gets sorted, but the ItemsControl doesn't. How can I make this work? Thanks! 回答1: You have to sort the CollectionView: List<MyObject> myInternalList = new List<MyObject>(); ... ICollectionView colView = CollectionViewSource.GetDefaultView(myInternalList); colView

问题 In a fresh Universal Windows Platform app, I am trying to set the Background of an ItemsControl. But it doesn't seem to do anything.

问题 I have an ItemsControl where I display a long list of objects. I display it in a wrappanel so the user does not need to scroll.

Here is my xaml: <ItemsControl ItemsSource="{Binding Inventory}"> <ItemsControl.ItemTemplate> <DataTemplate> <StackPanel> <Grid Width="300"> <Grid.ColumnDefinitions> <ColumnDefinition Width="200"/> <ColumnDefinition/> <ColumnDefinition Width="30"

问题 I have a list of a list of strings which is an adequate stand in for what I need to lay out. I've also read everywhere that in order to accomplish what I need to do, my best bet is an ItemsControl . The problem is that ItemsControl doesn't play nice with Grid out of the box. Fortunately I've found a few articles with code that has helped get me pointed in the right direction. Unfortunately, it's not everything I need. This is the DataContext with which I am working ( and I am pretty certain

问题 I am implementing an DragAndDrop-manager for wpf using attached properties. It works quite nice. But there is only one problem. To grab the dragged item i am using the visualtree. As example I want to have the listboxitem but the originalsource is the border of the listboxitem. So I just use one of my helper methods to search for the parent with the type of ListBoxItem. If I found that I get the data of it and drag that. But I dont want to have my DragAndDrop-manager aviable only while using

The numbers are in a queue, I used parallel programming skills to deal these items. When processing the item, the information is shown on the screen. Here I prefer ItemsControl. The expected result likes the image. I want to I borrowed the code for phone icon. <ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http:/

问题 I have a WPF UserControl which is dynamically created at runtime. Depending on user interaction, from 1-5 of these controls is created and should be added to the UI. I have an ObservableCollection<PlayerSpec> PlayerSpecViews in the xaml.cs code-behind. Initially I tried using a Grid and dynamically adding RowDefinitions but that wasn't working. The control would be scaled down in size. Then I tried using an ItemsControl but the binding was not adding the Control but instead the type name. How
